Mechanical Design Engineer

AmcaLos Angeles, CA, US Internship

Job Description

Amca is building airplanes for the 21st century, starting by designing new hardware that flies on today’s planes. Aviation was once humanity’s boldest ambition, but the industry hasn’t successfully built a new plane in 40 years. We don’t think it has to be this way.

Overview:

The Mechanical Design Engineering role is responsible for developing flight hardware for new and existing airframes. You will serve as the extreme owner of the product from concept through qualification, and eventually production handoff. Your day will consist of designing, analyzing, and building a wide range of fluid and structural systems. Most importantly you will own the relationship between customer level requirements and the build/test engineering teams.

Responsibilities:

  • Own design and prototyping of new mechanical hardware

  • Develop state-of-the-art, manufacturable, flow control devices (valves, regulators, solenoids) and mechanisms (actuators, switches, pistons). Question requirements, simplify, and accelerate aerospace component deliveries

  • Generate and maintain detailed drawings, component specifications, analysis and risk assessments. We believe design engineers should perform their own concept design, technical analysis and first unit builds – we minimize compartmentalized duties wherever possible

  • Spearhead root cause investigations that arise in development, production, and test. Implement corrective actions to prevent repeat failures

  • Set the standard for rigorous component design and qualification testing. As a member of an early-stage startup, you will be integral in defining company design and testing policies

  • Act as the extreme owner for the parts you work on, you will be expected to be the ultimate authority for components you develop and be able to work closely with customers and manufacturers as problems arise

  • Prototype new components at our in-house R&D lab. You will be expected to be intimately involved with any prototype development

  • Work with test engineering to define and execute qualification plans

  • Work closely with build engineers to ensure new designs are manufacturable at production facilities and DFM feedback is implemented

Basic Qualifications:

  • Bachelor's or advanced degree in aerospace engineering, manufacturing engineering, materials engineering, mechanical engineering or engineering physics

  • 1+ years of mechanical or fluids design, analysis, or build experience (student project team and internship experience qualifies)

  • Strong understanding of engineering first principles, specifically with regards to thermodynamics, fluid dynamics, and solid mechanics

Preferred Skills and Experience:

  • Strong interpersonal and collaborative skills, enthusiasm for problem solving, and desire to optimize modern aerospace production and design processes

  • 2+ years of professional experience in the field of aerospace/mechanical engineering

  • 2+ years of experience with GD&T concepts

  • Strong project management skills and effective communication of technical concepts across multi-disciplinary teams

  • Experience designing, building, testing and troubleshooting mechanical systems

  • Experience with pressurized components (valves, regulators, tubes, pipes, etc.)

  • Experience with finite element analysis (FEA) software packages

  • Experience with Siemens NX or other similar CAD package

  • Experience using test instrumentation and control components (e.g. pressure transducers, thermocouples, resistance temperature detectors, relays, solenoid valves, etc.)

Additional Requirements:

  • Travel to vendors and other Amca sites as needed

  • Able to work flexible hours and occasional weekend support as needed
